AI Technical Summary

Technical Problem

The prior art is prone to the risk of clamping force deviation and landing gear falling during the clamping and installation of aircraft landing gear, which reduces the practicality of the device.

Method used

An aircraft landing gear installation auxiliary equipment is designed, using a combination of lifting mechanism and clamping mechanism. The threaded rod and slider drive the installation plate and fixed box to move through the motor to achieve stable clamping of the aircraft landing gear, and the support plate is lifted by the telescopic cylinder to support the bottom of the landing gear, reducing the gravity burden of the clamping mechanism.

Benefits of technology

It realizes stable clamping and installation of the aircraft landing gear, avoids the risk of landing gear falling, and improves the practicality and user experience of the device.

Abstract

The utility model discloses an aircraft landing gear installation assistive device, which relates to the technical field of aircraft maintenance equipment, and comprises a movable base, the right part of the top end of the movable base is fixedly connected with a fixed box, the left part of the bottom end of the movable base is fixedly connected with a support frame, and the top end of the fixed box is fixedly connected with a lifting mechanism. A clamping mechanism is fixedly connected to the left end of the lifting mechanism, a bearing mechanism is fixedly connected to an inner cavity of the supporting frame, and the lifting mechanism comprises a first motor and a mounting plate. According to the auxiliary installation tool for the aircraft landing gear, by starting the telescopic cylinder, the telescopic cylinder drives the bearing plate to rise upwards, the bearing plate slides on the outer wall of the second guide rod, the bearing plate is limited and guided through the second guide rod, the bearing plate is more stable in the moving process, the bottom of the aircraft landing gear is borne through the bearing plate, and the installation efficiency of the aircraft landing gear is improved. And the downward gravity borne by the clamping mechanism is reduced, so that clamping is more stable, and the bearing effect is achieved.
